Re: US Split-Phase to EU Heat Pump Not Working

Re: Portable generator or not?

Re: Earthing the inverter
Not certain but I think the 240 volts is the RMS value rather than a typo. The peak voltage is higher.

Lot to ponder on there and I tend to the opinion (based on no more than intuition) that the simple graph tends to misrepresent the real situation.

I suspect it's not just the cycle rate which causes the problem.
My limited understanding of multi phase AC power is that the three phases are 120 degrees apart. When using a single phase one gets...
